To all whom it may concern:

Be it known that I, LUTHER SMITH, a citizen of the United States,residing at Norristown, in, the count of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements inRailway Ties, of which the following is a specification.

This invention relates to railway ties and more particularly toreinforced railway ties.

An object of the invention is to provide a reinforced concrete railwaytie with means for locking rails thereupon. v

, Another object of the invention is to provide a reinforced concretetie having means thereupon for securing a rail in a fixed position,whereby the laying of a track is greatly facilitated. 1 g

A further object of the invention is to provide a reinforced concretetie having thereupon means for securing rails thereupon in a fixedposition, the means for securing the rails in a fixed position beingformed upon the tie so as the rails thereupon at a standard gage.

"A further ob ect of my invention is to provide a reinforced concretetie havingv thereupon a locking memberpartially em bedded in the tie,and provided with means for mounting and securing in a lockedposition anadjustable member, whereby a rail may be securely clamped and supported.

A still further object of my invention is to provide a reinforcedconcrete railway. tie provided with a positive lockingmeans, and to soconstruct the same that it will be highly efficient in operation, yet ofmarked simplicity as a whole and in respect to each of its componentparts, so that its manufacture is economically facilitated both asregards'parts and their assembly. I

With theseand other objects in view which maybe incident to myimprovements, the invention consists in the parts and combinations to behereinafter set forth and claimed, with the understanding that theseveral necessary elementscomprising my invention, may be varied inconstruction, proportions and arrangement, without departing from thespirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown inthe. ac.-

to securely lock companying drawings means for carrying the same intopractical effect, without limitmg the improvements in their usefulapplications to the particularconstructions, which for the pur ose ofexplanation, have been made the su ject of illustration.

In the drawings forming a part of this specification: I v I Figure 1 isa perspective View illustratmg one end of my improved tie, a section ofthe rail being shown clamped thereto;

Fig. 2 is a perspective view of the lock- 1ng means detached from thetie and disassembled; I

,Fig. 3 isa side elevation of the locking mechanism in a closed orlocked position.

Referringby numerals to the drawings, 1" Y represents a railway tieconstructed in accordance with my invention. The tie com-.

prises a rectangular concrete casting having a plurality of' reinforcingrods 2 embedded therein. The side faces of the rectangular concretemember are provided with oppositely disposed and corres ondin dovetailslots or channels 3, at eac end t ereof.

Mounted upon the rectangular concrete member at each end thereof is aplate or saddle 4. The plate l is'bent to straddle and to conform withthe concrete member 1. The plate 4: is provided upon its face '5. with aflange 6 adapted for engagement with a flange of a rail 7. .The plate 4has oppositely disposed flanges 8 at'right angles to,

the body portion. Formed upon the ends of the flanges 8 are oppositelydisposed dovetailed channels 9 which engage or fit into the channels 3in the rectangular concrete member 1. The plate 4 is further provided:

with a boss or lug 10 having an aperture 11, the object offwhich willhereinafter appear.

'The plate 4 is a stationary member and is positioned or adjusted to therectangular concrete member 1 at the time of casting the concrete;member, however, the plate t may be mounted upon the rectangularconcrete member after the casting of the member has been completed,inwhich event the plate 4 would be secured to the concrete member 1 bya'transverse bolt, not shown.

An adjustable plate or saddle 12 is bent to straddle the rectangularconcrete member 1. The plate 12 is providedupon its top.

with a flange 13 adapted to engage a flange on the base of a rail. Theflange 13 is oppositely disposed with respect to the flange 6 upon thestationary plate t, when the parts are assembled. The plate 12 hasoppositely disposed and corresponding right angular flanges 14 whichengage the side faces of the concrete member 1. The flanges 14L areprovided upon their free ends with dovetail guides 15, oppositelydisposed with respect to each other. The guides 15 are adapted to engagethe guideways 9 upon the plate 4. The side flanges 14 are furtherprovided with bosses having apertures 16 therein. The apertures 16register with the apertures 11 in the stationary plate 8. Bolt 17 passesthrough the apertures 11 and 16. Taps 18 are threaded upon the bolts 17.By means of the bolt 17, the members 4- and 12 are securely lockedtogether in such a manner as to rigidly support rails 7, and to securelylock the same upon the rectangular member 1 in a predetermined spacedrelation which will in the general run of cases be thestandard gage.

lVhile I have shown and described the preferred embodiment of myinvention, I wish it to be understood that I do not confine myself tothe precise details of construction herein set forth, by Way ofillustration, as it is apparent that many changes and variations may bemade therein, by those skilled in the art, without departing from thespirit of the invention, or exceeding the scope of the appended claims.
